Anthropic on Monday unveiled two new AI models, Claude Fable 5.2 and Claude Mythos 5.2, as the OpenAI rival seeks to strengthen its market position ahead of its planned initial public offering. The exact date of the launch is not specified in the sources reviewed.
According to Dawn, Claude Fable 5.2 was designed for coding, reasoning and AI agent tasks and will be available more broadly. Claude Mythos 5.2 was developed for approved cybersecurity and life-sciences research, and access is restricted to approved organisations.
Dawn also reported that Anthropic said the new models can generate outputs up to 30 per cent faster than Claude 5.1 and communicate more clearly. According to the company, the models are priced at $8 per million input tokens and $40 per million output tokens, lower than previous Fable and Mythos releases.
These speed and pricing figures are company claims and have not been independently verified.
The launch follows Anthropic’s introduction of Claude Haiku 5.5 in October, as the startup expands its product portfolio ahead of a planned IPO. OpenAI, Alphabet’s Google and Meta Platforms have also rolled out new models focused on coding, reasoning and AI agents. No responses from those companies were included in the sources reviewed.
A Japan Times headline and short excerpt says the IPO comes as a waiting period ends, despite last week’s swoon in AI-related stocks. Only that headline and excerpt were available, so the IPO timing and details of the stock decline are not confirmed by a full article.
A Reddit post in r/news, based on a headline, reports that a plan for an IPO of nearly $70 billion briefly circulated to banks before being retracted. No full report or company response was available to confirm this.
Anthropic is expected to make its case to investors for going public as its IPO waiting period ends, according to Japan Times, though no date has been confirmed. The company has not confirmed the date or size of the offering in the sources reviewed.
The main product details rest on a single outlet, Dawn, and the performance and pricing claims come from Anthropic itself.
